#149: N35 Neodymium Ring Magnet (3mm Hole, 10mmx3mm)

R15.55

This Strong N35 grade Neodymium Ring Magnet is extremely strong for its size and very has many uses in electromagnetism & radio. Their main advantage is their low weight and size, which means they are easily transported and very practical to use.

• Neodymium magnets (AKA Neo, Rare Earth, NIB, NdFeB), invented in the 1980s, are the strongest and most affordable type of rare-earth magnet. 

• Made of an alloy of neodymium, iron and boron (Nd2Fe14B). 

• Used in numerous applications requiring strong, compact permanent magnets, such as electric motors, hard drives, magnetic hold downs, jewelry clasps and power generation (wind & hydro turbines). 

• They have the highest magnetic field strength and have a high coercivity (which makes them magnetically stable).
  Strong enough even to pin a A4 paper.

• Universities or research labs sometimes request such small magnets, for instance to secure tiny parts under the microscope.

• These magnets are incredibly strong for their small size and work great for crafts, repairs, hanging items on your fridge, etc.
